The performance of DSInternals when reading ntds.dit files is definitely slower than LDAP for several reasons:
- .NET Framework adds a lot of overhead to Win32 API calls and ~100 such calls need to be performed to read a single account.
- I have not implemented any paralelism to DSInternals.
- My code does many unnecessary memory allocations when decrypting AD data.
Having said that, DSInternals is much faster than competing tools, as it heavily utilizes database indices when searching for user accounts.
As far as I remember, reading 1M accounts from ntds.dit might take an hour or two.
